Different ones for different reasons - if going for longer runs and carrying liquids I use the Amphipod (and Dexcom goes in the clip-on case Dexcom provides). Spibelt can carry a lot of "stuff" - tends to bounce for me the more that I try to cram into it (so again Dexcom usually goes in the Dex clip-on case). My 12 y.o. daughter carries her Dexcom in her Spibelt and has no bouncing problems though. PakBara is pretty solid, I use the clip on version of that one. Pump can also go into it, but a tight fit once you've got all of that loaded in the case. I've also used 2 belts at a time (Spibelt/Pak for some combination of meter/strips/gels/keys Amphipod for water/gels/keys).
